FIELD

The present disclosure relates to a technical field concerning an output device and an operation unit cover. In particular, the present disclosure relates to a technical field in which the operation unit cover is formed to have a given shape by using rubber materials to thereby prevent the operation unit cover from being broken.

BACKGROUND

There exists an output device which houses a portable device such as a music reproduction device and an image reproduction device in an internal space and which outputs audio and images outputted from the housed portable device to the outside.

As one of the above output devices, there is one in which a lid body can be opened and closed with respect to a case body, a portable device is mounted in the internal space with the lid body in an opened state and the portable device is stored and held in the internal space by connecting the lid body to the case body for sealing the portable device (For example, refer to JP-A-2007-313020 (Patent Document 1).

In the output device described in Patent Document 1, for example, a speaker unit for outputting audio outputted from the portable device to the outside is provided at the case body. A window portion is formed in the lid body and a transparent operation unit cover having flexibility is attached so as to cover the window portion.

In a state in which the lid body is connected to the case body, the lid body is locked with respect to the case body due to buckles pivotally supported at the case body, as a result, the internal space is sealed for securing the waterproof property. In the state in which the lid body is locked with respect to the case body and the portable device is housed in the internal space, the operation unit cover is pressed onto the portable device and the portable device is held, therefore, unnecessary movement of the portable device in the internal space is prevented.

When a user performs operation of an operation unit of the portable device with the operation unit cover from the outer surface side, for example, audio outputted from the portable device can be outputted to the outside.

SUMMARY

However, the operation unit cover is formed in a planar shape in the output device described in Patent Document 1, therefore, the amount of stretch in the operation unit cover is large in the state in which the portable device is held by the operation unit cover. As the load with respect to the operation unit cover is high, the operation unit cover is liable to be broken when the output device is accidentally fallen or some other occasions. There is also the danger that the operation unit cover is caught between the portable device and part of the lid body or the case body at the time of falling of the output device and some other cases, which may also lead to the breaking of the operation unit cover.

Particularly, in the case where the portable device is formed in a rectangular parallelepiped shape, the load with respect to portions of the operation unit cover pressing corner portions of the portable device is extremely high, which increases probability that the portions pressing the corner portions will be broken.

As the amount of stretch in the operation unit cover is large, high load is accordingly applied from the operation unit cover to the lid body to which the operation unit cover is attached, which may cause deformation of the lid body to be an obstacle for open/close operation of the lid body.

Particularly, the output device is often used under environment of high temperature such as outdoor or indoor environment. There is also a disadvantage that the breaking of the operation unit cover, the deformation of the lid body and so on are more liable to occur when the amount of stretch in the operation unit cover is further increased due to variation of temperature.

In view of the above, it is desirable to provide an output device and an operation unit cover which can prevent the operation unit cover from being broken or being damaged.

DETAILED DESCRIPTION

Hereafter, the best mode for carrying out the present disclosure will be explained with reference to the attached drawings.

An output device according to an embodiment of the present disclosure is, for example, a device outputting audio and images outputted from a portable device housed in an internal space to the outside, which includes a case body and a lid body connected to the case body so as to pivot about a hinge portion.

In the following explanation, directions are shown in a normal use state of the output device for convenience of explanation. The side where the case body is positioned is assumed to be the back and the side where the lid body is positioned is assumed to be the front in a state in which the portable device is housed in the internal space. Directions are also shown on the assumption that the hinge portion is positioned on a lower side and speaker units are positioned right and left.

The directions of up, down, front, back, left and right which will be described below are shown for convenience of explanation, and the present technology is not exclusively applied to these directions.

[Structure of an Output Device]

An output device 1 has a structure in which a case body 2 and a lid body 3 are connected through a hinge portion provided at a lower end portion, and the lid body 3 can pivot with respect to the case body 2 about the hinge portion 4.

The case body 2 is formed to have, for example, an outer shape of rather oval in landscape orientation, and a portion ranging from an outer circumferential surface to an outer peripheral portion of a back surface is formed in a curved surface which is convex outward (refer to FIG. 2). On an upper surface of the case body, operation buttons 5, 5 are arranged right and left so as to be apart from each other (refer to FIG. 1 and FIG. 2). The operation buttons 5, 5 function as, for example, volume adjustment buttons for adjusting volume of audio outputted from a later-described portable device.

At a lower end portion of the case body 2 on the back side, a supporting stand 6 is pivotally connected (refer to FIG. 2). An upper end portion of the supporting stand 6 is connected to the case body 2. The output device 1 can be placed in a standing state by pivoting the supporting stand 6 to be pulled out from the case body 2 (refer to FIG. 5).

At right and left portions on both sides of the case body 2 on the upper side, shallow cutout portions for arrangement 2 a, 2 a are formed (refer to FIG. 6). Buckles 7, 7 are pivotally supported at right and left portions on both sides of the case body 2 respectively on the upper side. The buckles 7, 7 can pivot between a locked position (refer to FIG. 1 and FIG. 2) and a lock release position (refer to FIG. 4 and FIG. 6), and portions other than front end portions are housed in the cutout portions for arrangement 2 a, 2 a respectively in the locked position.

The buckle 7 includes a body 8, locking claws 9, 9 protruding inward from upper-and-lower both end portions (both end portions in a circumferential direction) in the front end portion of the body 8 and fulcrum shaft portions 11, 11 provided on the inner surface side of the body 8, which are integrally formed (refer to FIG. 4, FIG. 7, FIG. 8 and FIG. 9).

The locking claw 9 is formed in a triangular shape so as to be elastically deform with respect to the body 8, in which an locking protrusion 10 protruding backward is provided at a back surface of a tip portion (refer to FIG. 8 and FIG. 9). The locking protrusion 10 includes a first inclined surface 10 a positioned at the tip portion side and inclining so as to be displaced backward as coming close to the body 8 and a second inclined surface 10 b continuing from the first inclined surface 10 a and inclining so as to be displaced forward as coming close to the body 8.

The buckles 7, 7 are positioned so that outer surfaces continue to an outer surface of the case body 2 (refer to FIG. 5 and FIG. 9) in the state of the locked position and are positioned so that front end portions are positioned on the outer side of the outer surface of the case body 2 in the state of the lock release position (refer to FIG. 6 and FIG. 8).

On a front surface 2 b of the case body 2, a housing portion 12 is provided at the center in the right and left direction (refer to FIG. 4 and FIG. 7). A housing rib 13 formed to have an approximately rectangular-frame shape in portrait orientation is provided in the housing portion 12 and the inside of the housing rib 13 is formed as a housing recess 14.

The housing rib 13 includes first restriction walls 15, 15 positioned vertically apart from each other and extending right and left and second restriction walls 16, 16 positioned horizontally apart from each other and extending above and below. The protrusion amount (height) of the first restriction walls 15, 15 to the front direction from the front surface 2 b of the case body 2 is constant, and the protrusion amount of the second restriction walls 16, 16 to the front direction from the front surface 2 b of the case body 2 is increased from the center of the wall in the vertical direction toward upper and lower directions.

The housing rib 13 includes an edge surface 13 a whose outer surface faces the front, an outer peripheral surface 13 b continuing from an outer edge of the edge surface 13 a and an inner peripheral surface 13 c continuing from an inner edge of the edge surface 13 a. At the center of the second restriction walls 16, 16 in the vertical direction, recesses for removal 16 a, 16 a are respectively formed. The recesses for removal 16 a, 16 are communicated with the housing recess 14 and the edge surface portion 13 a is formed in an approximately arc shape which is convex backward.

In the housing rib 13, a width of the edge surface 13 a of the first restriction walls 15, 15 (a width H1 of an upper and lower edges) is formed to be smaller than a width of the edge surface 13 a of the second restriction walls 16, 16 (a width H2 of right and left edges) as shown in FIG. 4.

The width H1 of the edge surface 13 a of the first restriction walls 15, 15 is formed to be smaller as described above, thereby reducing the size of the housing rib 13 in the longitudinal direction which is the vertical direction to the minimum and miniaturizing the output device 1.

Concerning spaces between the inner peripheral surface 13 c of the housing rib 13 and an outer peripheral surface of a portable device 500 (refer to FIG. 10), spaces between the portable device 500 and the second restriction walls 16, 16 in the right and left direction are liable to be smaller than spaces between the portable device 500 and the first restriction walls 15, 15 in the vertical direction when considering the size of the portable device 500. Therefore, it is more likely that contact occurs between the portable device 500 and the second restriction walls 16, 16 than between the device and the first restriction walls 15, 15. The width H2 of the edge surface 13 a in the second restriction walls 16, 16 is formed to be larger, rigidity of the second restriction walls 16, 16 can be increased to thereby prevent damage occurring when the portable device 500 touches the walls.

A shallow attachment recess 17 a opening to the front is formed at the battery lid 17 (refer to FIG. 7). A nonslip sheet 18 made of rubber materials such as silicon rubber is attached to the attachment recess 17 a of the battery lid 17. Arrangement of the nonslip sheet 18 to the housing recess 14 prevents slipping of the portable device 500 to be housed in the housing recess 14, which provides stability of a housing state of the portable device 500 in the housing recess 14.

The nonslip sheet 18 is detachable with respect to the attachment recess 17 a, therefore, the nonslip sheet 18 can be washed by removing the nonslip sheet 18 from the attachment recess 17 a.

In the housing recess 14, a cable arrangement groove 14 b opening to the front and a connector arrangement groove 14 c opening to the front are continuously formed in the vertical direction at a lower side of the battery lid 17.

The operation unit cover 30 is attached to the lid body 3 by fitting the inner protruding ridge 33 b and the outer protruding ridge 33 c to the holding groove 27, fitting the first to-be-attached protrusions 33 d, 33 d to the first attachment grooves 28, 28 respectively and fitting the second to-be-attached protrusions 33 e, 33 e, . . . to second attachment grooves 29, 29, . . . respectively.

[Open/Close Operation of the Lid Body]

Hereinafter, open/close operation of the lid body 3 will be explained.

When the lid body 3 is an opened state, the portable device 500 is inserted in the housing recess 14 of the housing portion 12 and arranged there (refer to FIG. 16). At the time of arranging the portable device 500 in the housing recess 14, the connector 400 is connected to the connection terminal portion 501. At this time, the connector 400 and the cable 300 can be pulled forward from the connector arrangement groove 14 c and the cable arrangement groove 14 b respectively as described above, therefore, the connector 400 can be connected to the connection terminal portion 501 easily.

The portable device 500 arranged in the housing recess 14 is placed on the placing surface 14 a in a state in which a display surface 502 on which images and characters are displayed and an operation unit 503 for performing given operation face the front. In the state in which the portable device 500 is placed on the placing surface 14 a, slipping of the portable device 500 is prevented by the nonslip sheet 18 attached to the battery rid 17, which allows the arrangement state of the portable device 500 to be stable.

In the opened position where the lid body 3 is opened, the buckles 7, 7 supported on the case body 2 are pivoted to the lock release position.

When the lid body 3 is pivoted about the hinge portion 4 to a closed position, the operation unit cover 30 is fitted onto the housing rib 13 of the case body 2 (refer to FIG. 14 and FIG. 15), and the housing recess 14 and the portable device 500 arranged in the housing recess 14 are closed by the operation unit cover 30.

In the state in which the operation unit cover is fitted onto the housing rib 13, the outer periphery of the front surface portion 31 is positioned so as to abut on or close to the edge surface 13 a of the housing rib 13 and the circumferential surface portion 32 is positioned so as to abut on or close to the outer peripheral surface 13 b.

The flange portion 33 of the operation unit cover 30 is in a state in which a back surface of the base portion 33 a of the flange portion 33 is pressed on the front surface 2 b of the case body 2. At this time, a portion between the inner protruding ridge 33 b and the outer protruding ridge 33 c of the base portion 33 a of the flange portion 33 is pressed on the waterproof rib 19, which gives waterproof property of the housing recess 14. As the portion of the base portion 33 a pressed on the waterproof rib 19 is liable to be elastically deformed between the inner protruding ridge 33 b and the outer protruding ridge 33 c, adhesion with respect to the waterproof rib 19 is good, therefore, the housing recess 14 and the portable device 500 arranged in the housing recess 14 can be waterproofed.

In the state in which the lid body 3 is pivoted to be in the closed position, the portable device 500 is held by portions other than part of the front surface portion 31 of the operation unit cover 30, for example, by the holding surface portion 31 a or by the holding surface portion 31 a and part of the inclined surface portions 31 b, 31 c (refer to FIG. 14). Therefore, the movement of the portable device 500 in the housing recess 14 is restricted and the stable housing state of the portable device 500 in the housing recess 14 can be secured.

In the above state, the portable device 500 is held by the holding surface portion 31 a of the operation unit cover or by the holding surface portion 31 a and part of the inclined surface portions 31 b, 31 c, therefore, all or part of the inclined surface portions 31 b, 31 c does not touch the portable device 500. Consequently, the load applied from the portable device 500 to the operation unit cover 30 is small and the amount of stretch in the operation unit cover 30 is small, therefore, the breaking of the operation unit cover 30 can be prevented also in the case where the output device 1 is accidentally fallen or some other occasions.

Additionally, all or part of the inclined surface portions 31 b, 31 c does not touch the portable device 500, therefore, there is no danger that the operation unit cover 30 is caught between the portable device 500 and part of the case body 2 or the lid body 3 at the time of falling of the output device 1 and some other cases, which prevents the breaking of the operation unit cover 30 caused by being caught.

Moreover, the load with respect to the portion of the front surface portion 31 pressing corner portions of the portable device 500 is also small, which can prevent the breaking in the portion.

Furthermore, the inclined surface portions 31 b, 31 c are provided in the front surface portion 31, therefore, a stretching margin of the front surface portion 31 is larger than in the case where the entire front surface portion 31 is formed in a planar shape, which can accordingly reduce the load applied from the operation unit cover 30 to the lid body 3. Consequently, the load with respect to the lid body 3 by the stretching of the operation unit cover 30 is reduced, thereby preventing deformation of the lid body 3 and securing smooth open/close operation of the lid body 3.

Particularly, the output device is often used under environment of high temperature such as outdoor or indoor environment. The load with respect to the operation unit cover 30 and the lid body 3 is reduced even when the operation unit cover 30 is stretched due to temperature variation by increasing the stretching margin of the operation unit cover 30, which can prevent the breaking of the operation unit cover 30 and deformation of the lid body 3 when temperature varies.

In the output device 1, the size of the housing portion 12 is prescribed to a fixed size by the housing rib 13 and the operation unit cover 30 is formed in a box shape having the front surface portion 31 and the circumferential surface portion 32 so as to correspond to the size and shape of the housing rib 13. Accordingly, the housing portion 12 and the window portion 3 a of the lid body are formed to have the minimum size, which realizes miniaturization of the output device 1.

As the housing rib 13 protruding forward from the front surface 2 b is provided in the housing unit 12, for example, infiltration of moisture to the housing recess 14 occurring when moisture is attached to the front surface 2 b can be prevented, which improves waterproof property.

Furthermore, when the position of the portable device 500 housed in the housing recess 14 is moved due to the shock, vibration and so on, the moved portable device 500 abuts against the housing rib 13 and the movement is restricted. Therefore, the state in which the portable device 500 is held on the front surface portion 31 of the operation unit cover 30 can be maintained even when the shock, vibration and so on occur.

Additionally, when the portable device 500 housed in the housing recess 14 is moved, all or part of the inclined surfaces 31 b, 31 c of the operation unit cover 30 does not touch the portable device 500. Therefore, when the portable device 500 housed in the housing recess 14 is moved, there is no danger that the operation unit cover 30 is caught between the portable device 500 and part of the case body 2 or the lid body 3 when the output device 1 is fallen and some other occasions, which prevents the breaking of the operation unit cover 30 caused by being caught.

As the connector 400 to be connected to the connection terminal portion 501 of the portable device 500 is positioned behind the inclined surface portion 31 c of the operation unit cover 30, the connector 400 does not touch the operation unit cover 30 and the load from the operation unit cover 30 is not applied to the connector 400. Consequently, the operation unit cover 30 does not affect the connecting state between the connection terminal portion 501 of the portable device 500 and the connector 400, which secures the stable connecting state between the connection terminal portion 501 and the connector 400.

When the buckles 7, 7 are pivoted from the lock release position to the locked position in the state in which the lid body 3 is pivoted to the closed position, the lid body is locked with respect to the case body 2 in the closed position as explained below (refer to FIG. 17 to FIG. 19).

As the buckle 7 is pivoted from the lock release position toward the locked position, the first inclined surface 10 a of the locking protrusion 10 provided at the locking claw 9 of the buckle 7 touches the first inclined surface 24 a of the to-be-locked protrusion 24 provided at the to-be-locked piece 23 of the lid body 3 (refer to FIG. 17).

When the buckle 7 is further pivoted toward the locked position, the first inclined surface 10 a of the locking protrusion 10 makes sliding contact with the first inclined surface 24 a of the to-be-locked protrusion 24, and the locking claw 9 and the to-be-locked piece 23 are elastically deformed, as a result, the locking claw 9 climbs over the to-be-locked piece 23 (refer to FIG. 18).

When the buckle 7 is further pivoted toward the locked position, the second inclined surface 10 b of the locking protrusion 10 makes sliding contact with the second inclined surface 24 b of the to-be-locked protrusion 24, and the locking claw 9 and the to-be-locked piece 23 are elastically returned, as a result, the second inclined surface 10 b of the locking protrusion 10 is engaged with the second inclined surface 24 b of the to-be-locked protrusion 24 (refer to FIG. 19). The second inclined surface 10 b of the locking protrusion 10 is engaged with the second inclined surface 24 b of the to-be-locked protrusion 24, thereby allowing the buckle 7 to be in the locked position and allowing the lid body 3 to be locked with respect to the case body 2.

As described above, when the lid body 3 is locked with respect to the case body 2, the flange portion 33 of the operation unit cover 30 is pressed onto the portion around the housing rib 13 on the front surface 2 b of the case body 2, which secures good waterproof property with respect to the housing portion 12.

In the state in which the lid body 3 is locked with respect to the case body 2, operation is performed by a finger 100 with respect to the operation unit 503 of the portable device 500 which is pressed onto the placing surface 14 a of the housing recess 14 by the operation unit cover 30 (refer to FIG. 20). When the operation is performed with respect to the operation unit 503 of the portable device 500, for example, audio output from the portable device 500 is transmitted to the speakers 21, 21 through the connector 400, as a result, audio is outputted from the speakers 21, 21. The audio outputted from the speakers 21, 21 is outputted to the outside through the output holes 20 a, 20 a, . . . formed in the speaker arrangement portions 20, 20 of the case body 2 and the audio output holes 3 b, 3 b, . . . formed in the lid body 3.

Additionally, images displayed (outputted) on the display surface 502 of the portable device 500 are transmitted through the front surface portion 31 of the operation unit cover 30 and outputted to the outside.

In the state in which the lid body 3 is locked with respect to the case body 2, the lock of the lid body 3 with respect to the case body 2 is released by pivoting the buckles 7, 7 from the locked position to the lock release position.

The pivoting operation from the locked position to the lock release position of the buckle 7 is a reverse operation to the pivoting operation from the lock release position to the locked position. That is, the release of the lock of the lid body 3 with respect to the case body 2 is performed in the manner in which the buckle 7 is pivoted from the locked position to the lock release position, the locking claw 9 and the to-be-locked piece 23 are elastically deformed and the locking claw 9 climbs over the to-be-locked piece 23, then, the buckle 7 is further pivoted toward the lock release position and the locking claw 9 and the to-be-locked piece 23 are elastically returned.

The lid body 3 is pivoted from the closed position to the opened position in the state in which the lock of the lid body 3 with respect to the case body 2 is released, thereby removing the portable device 500 from the housing access 14.

The removal of the portable device 500 from the housing recess 14 can be easily performed by inserting two fingers into the housing recess 14 through the recesses for removal 16 a, 16 a formed in the second restriction walls 16, 16 of the housing rib 13 and holding the portable device 500 from right-and-left both sides.

The recesses for removal 16 a, 16 a are formed in the housing rib 13 as described above, therefore, the portable device 500 can be easily removed from the housing recess 14, which improves user-friendliness of the output device 1.
